Fig. 2 illustrates a flow chart of a method 200 of locating a position of an exhibit, the method 200 being adapted for execution in a computing device (e.g., the computing device 100 shown in fig. 1), in accordance with one embodiment of the invention. As shown in fig. 2, the method 200 begins at step S210.
It is explained that the method for positioning the position of the exhibited article is suitable for uniformly placing the exhibited article on the exhibition stands of the 3D exhibition hall with the regular shape, the exhibition stands are uniformly placed around the inside of the 3D exhibition hall, and the shape and the size of each exhibition stand are the same. The 3D exhibition hall with the regular shape specifically means that a bird's eye view plan of the 3D exhibition hall is regular polygon or circular. For example, regular triangles, squares, regular hexagons, etc.
In step S210, a serial number for each display stand is determined from the coordinate system on which the 3D display hall is designed. Further, the serial number of each display stand is determined from a two-dimensional coordinate system in the aerial plan of the 3D display house. Specifically, in the plane of the horizontal axis and the vertical axis, the serial number of each display stand is determined in a counterclockwise direction from the positive half axis of the horizontal axis.
For example, the bird's eye view plan of a 3D exhibition hall is regular hexagon, and six exhibition stands are uniformly placed in the exhibition hall. According to one embodiment of the present invention, the serial numbers of the six stands can be calibrated sequentially from the positive half axis of the horizontal axis x in a counterclockwise direction in order from small to large, and the specific result of the calibration can be seen in fig. 3.
Step S220 is then carried out, and the distance between the center point and the exhibit identification point is obtained according to the coordinates of the center point of the 3D exhibition hall and the coordinates of the preset exhibit identification point. The initial position of an exhibit can be pre-played by 3D exhibition hall designers when designing the 3D exhibition hall. The preset exhibition identification point refers to the initial point reserved by the 3D exhibition staff in the exhibition hall. Wherein, the exhibit can be the exhibition trolley.
According to one embodiment of the invention, the distance from each exhibit to the center point of the exhibit may be set to be the distance from the center point of the exhibit to the identity point of the exhibit. Like this, all exhibits just are in regard as the centre of a circle with the exhibition center point, regard as the circle of radius with the distance between center point and the sign point (see fig. 3) to can strengthen the aesthetic property of exhibition hall, promote user's experience.
In some embodiments, the distance between the center point and the exhibit identification point may be obtained according to the coordinates of the center point of the 3D exhibition hall and the coordinates of the preset exhibit identification point by the following formula.
Wherein r is the distance between the center point of the exhibition hall and the preset exhibit mark point, xdiff is the horizontal coordinate difference between the center point of the exhibition hall and the preset exhibit mark point, and ydiff is the vertical coordinate difference between the center point of the exhibition hall and the preset exhibit mark point.
In addition, considering that 3D exhibition hall designers mostly set the exhibit mark point on the abscissa axis x, the distance between the center point and the exhibit mark point can also be obtained by calculating the horizontal coordinate difference between the center point of the exhibition hall and the preset exhibit mark point. That is, the absolute value of the horizontal coordinate difference between the center point of the exhibition hall and the preset exhibit mark point is used as the distance between the center point of the 3D exhibition hall and the preset exhibit mark point.
Step S230 is then performed to obtain the degree of the increment angle according to the number of display stands. The incremental angle refers to an included angle between connecting lines of two end points and a central point on the same side of two adjacent display stands. Or, two adjacent stands increase in angle with reference to the axis of abscissa x. The incremental angle between display stand one and display stand two in fig. 3 is angle a. It can be seen that the degree of the increasing angle is the difference in degrees of the angle formed by the adjacent two stands and the positive half axis of the abscissa. As the exhibition stands are uniformly arranged around the exhibition hall and the shape and the size of each exhibition stand are the same, the incremental angle between any two adjacent exhibition stands has equal degrees. According to one embodiment of the present invention, the degree of the incremental angle may be obtained by the following equation.
addangle=360°/stagecount (2)
Wherein addangle is the degree of the increasing angle, stagecount is the number of stands.
Step S240 is then entered, and the degree of the included angle between two adjacent showcases on each exhibition stand is obtained according to the number of exhibition stands, the degree of the included angle between two adjacent showcases on each exhibition stand, and the number of the showcases placed on each exhibition stand. The included angle between two adjacent display stands refers to an included angle between two end points on adjacent sides of two adjacent display stands and a connecting line of a center point of the display house, and the included angle between the display stand two and the display stand three in fig. 3 is an angle b. According to one embodiment of the invention, all the exhibition stands are uniformly placed around the 3D exhibition hall, and the size and the shape of each exhibition stand are the same, so that the degrees of the included angle between any two adjacent exhibition stands are equal (the degrees of the included angle between the two adjacent exhibition stands are preset by a designer of the 3D exhibition hall). Based on the number of stands, the number of degrees of included angles between two adjacent stands, and the number of items of display placed on each stand, in some embodiments, the number of degrees of included angles between two adjacent stands can be obtained by the following equation.
carangle i =(360°/stagecount-gapangle)/(stagecarcount i +1) (3)
Wherein, carange i For the degree of the included angle between two adjacent exhibits on the exhibit i, gap is the degree of the included angle between two adjacent exhibits, and stagecarcounti is the number of exhibits on the exhibit i.
In this description, display i represents the i-th display in a 3D display. Further, from the positive half axis of the abscissa axis x, the display i is the i-th display in the 3D display, viewed in the counterclockwise direction.
The serial number of each display stand, the distance between the center point and the display product identification point, the degree of the increasing angle between two adjacent display stands and the degree of the included angle between two adjacent display products on each display stand are obtained through the steps. Then in step S250, the position of each exhibit on each exhibit may be obtained according to the obtained serial number of each exhibit, the distance between the center point and the exhibit identification point, the degree of the increasing angle, the degree of the included angle between two adjacent exhibits, and the degree of the included angle between two adjacent exhibits on each exhibit.
According to one embodiment of the invention, the location of each exhibit on each display stand may be obtained by the following equation.
x m,n =r*cos(addangle*(m-1)+carangle m *n+gapangle/2) (4)
y m,n =r*sin(addangle*(m-1)+carangle m *n+gapangle/2) (5)
Wherein m is the serial number of the exhibition stand, n is the serial number of the exhibition stand on m, and x is the serial number of the exhibition stand m,n 、y m,n Respectively the abscissa and the ordinate of the exhibit n on the exhibit m, r is the distance between the center point and the exhibit mark point, and carange m Is the degree of the included angle between two adjacent exhibits on the exhibit table m.
As can be seen, the coordinates of each exhibit in the exhibition hall are obtained through step S250. Two points, one of which is described herein, are coordinates of a center point of an exhibit, and since the dimensions of the exhibit and the stand are much larger than those of the exhibit, the dimensions of the exhibit need not be considered. Secondly, the serial numbers of the exhibits on each exhibition stand involved in the steps refer to serial numbers which are sequentially set on each exhibition stand from small to large in a anticlockwise direction. That is, the exhibit n on the exhibit m is the nth exhibit from the counterclockwise direction on the exhibit m, and see, for example, the serial number of each exhibit marked on the exhibit two in fig. 3.
In addition, the serial numbers of the display stands and the serial numbers of the exhibits in some 3D exhibitions may not be calibrated according to the methods of embodiments of the invention. For the 3D exhibition hall, the positioning method of the exhibits in the invention can be used for acquiring the position of each exhibit calibrated by the calibration method of the invention, and then the position of each exhibit is acquired by using the corresponding relation between the exhibit and the exhibit in the exhibition hall.
Obviously, by utilizing the method for positioning the exhibits in the 3D exhibition hall, each exhibit can be quickly placed at a corresponding position, the true uniform placement of the exhibits can be realized, the attractiveness of the exhibition hall is enhanced, and the experience of a user can be further improved.

Wherein, this positioner is suitable for evenly putting the showpiece on the stand of 3D exhibition hall, and the stand is evenly put in 3D exhibition hall, and the shape, the size of every stand are the same, and the aerial view plane view of 3D exhibition hall is regular polygon or circular.
